According to a source, it is a present progressive tense. The present progressive tense is a verb tense that means the action is continuing or in the act right now. “To be” verb is mainly used to indicate and identify this verb tense present and the applying –ing of the present participle of the verb word used in the sentence. Hence based on the given sentence above we can apply the present progressive tense as:
For example:
<span>The journalism staff is typing the yearbook copy, but another company is printing the book.</span>
B for sure. The other ones don't really work that well grammatically speaking.<span />
The prefix spelling rule does apply to suffixes because it helps people understand the words better so they can read correctly instead of having to guess and get it wrong possibly.
Hope this helps. :)
